Adjusting the front fork This front fork is equipped with air
valves for adjusting the spring rate.
EW000035
WARNING
@ Always adjust both fork legs equal-
ly, otherwise poor handling and loss
of stability may result. @
Adjust the spring rate as follows.
1. Elevate the front wheel by placing
the motorcycle on the centerstand.NOTE:@ When checking and adjusting the air
pressure, there should be no weight on
the front end of the motorcycle. @2. Remove the air valve cap from
each fork leg.3. Check the air pressure in each
fork leg with an air pressure
gauge.
NOTE:@ An optional air pressure gauge is avail-
able at a Yamaha dealer. @4. To increase the spring rate and
thereby harden the suspension,
increase the air pressure with an
air pump or compressed air. To
decrease the spring rate and
thereby soften the suspension, de-
crease the air pressure by pushing
each valve stem down.

4-PRE-OPERATION CHECKSThe condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.

Final gear oil The final gear case must be checked
for oil leakage before each ride. If any
leakage is found, have a Yamaha deal-
er check and repair the motorcycle. In
addition, the final gear oil must be
changed as follows at the intervals
specified in the periodic maintenance
and lubrication chart.
1. Place the motorcycle on the cen-
terstand.
2. Place an oil pan under the final
gear case to collect the used oil.3. Remove the oil filler bolt and drain
bolt to drain the oil from the final
gear case.
4. Install the final gear oil drain bolt,
and then tighten it to the specified
torque.
5. Add the specified amount of the
recommended final gear oil, and
then install and tighten the oil filler
bolt.
NOTE:@ GL4 is a quality rating. Hypoid gear oils
rated GL5 or GL6 may also be used. @
EW000066
WARNING
@ l
Make sure that no foreign mate-
rial enters the final gear case.
l
Make sure that no oil gets on
the tire or wheel.
@6. Check the final gear case for oil
leakage. If oil is leaking, check for
the cause.
1. Final gear oil filler bolt
2. Correct oil level
3. Final gear oil drain bolt
Tightening torque:
Final gear oil drain bolt:
23 Nm (2.3 m·kg)
Recommended final gear oil:
Hypoid gear oil SAE 80 (API GL4)
or multigrade hypoid gear oil
SAE 80W-90
Oil quantity:

WARNING
@ l
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
motorcycle with excessively
worn tires decreases riding sta-
bility and can lead to loss of
control.
l
The replacement of all wheel-
and brake-related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience.
@
Tire information
This motorcycle is equipped with tube
tires.
EW000078
WARNING
@ l
The front and rear tires should
be of the same make and de-
sign, otherwise the handling
characteristics of the motor-
cycle cannot be guaranteed.
l
After extensive tests, only the
tires listed below have been ap-
proved for this model by
Yamaha Motor Co., Ltd.
@CE-10EEAU00684
WARNING
@ This motorcycle is fitted with super-
high-speed tires. Note the following
points in order to make the most ef-
ficient use of these tires.l
Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super
high speeds.
l
Brand-new tires can have a rela-
tively poor grip on certain road
surfaces until they have been
“broken in”. Therefore, it is ad-
visable before doing any high-
speed riding to ride conserva-
tively for approximately 100 km
after installing a new tire.
l
The tires must be warmed up
before a high-speed run.
l
Always adjust the tire air pres-
sure according to the operating
conditions.

Cast wheels To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points
regarding the specified wheels.l
The wheel rims should be checked
for cracks, bends, warpage or
damage before each ride. If any
damage is found, have a Yamaha
dealer replace the wheel. Do not
attempt even the smallest repair to
the wheel. A deformed or cracked
wheel must be replaced.
l
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.
l
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for it
to develop its optimal characteris-
tics.
l
After repairing or replacing a tire,
tighten the valve stem nut and
locknut to the specified torques.
EAU00695
Clutch lever free play Since this model is equipped with a hy-
draulic clutch, adjusting the clutch lever
free play is not needed. However, it is
necessary to check the clutch fluid lev-
el and check the hydraulic system for
leakage before each ride. If the clutch
lever free play does become exces-
sive, and shifting becomes rough or
clutch slippage occurs, causing poor
acceleration, there may be air in the
clutch system. If there is air in the hy-
draulic system, have a Yamaha dealer
bleed the system before operating the
motorcycle. Tightening torques:
Valve stem nut:
1.6 Nm (0.16 m·kg)
Valve stem locknut:
1.6 Nm (0.16 m·kg)

Checking the steering Worn or loose steering bearings may
cause danger. Therefore, the operation
of the steering must be checked as fol-
lows at the intervals specified in the pe-
riodic maintenance and lubrication
chart.
1. Place a stand under the engine to
raise the front wheel off the
ground.
EW000115
WARNING
@ Securely support the motorcycle so
that there is no danger of it falling
over. @
2. Hold the lower ends of the front
fork legs and try to move them for-
ward and backward. If any free
play can be felt, have a Yamaha
dealer check or repair the steer-
ing.
